Ocean currents control the climate around the world. When they suddenly stop, it unleashes an endless cascade of weather disasters including blizzards, superstorms, drought and rapid sea level rise.
On 26 April 1986, reactor number four at the Chernobyl Nuclear Power Plant blew up. Forty-eight hours later the entire area was evacuated. Over the following months there were stories of mass graves and dire warnings of thousands of deaths from radiation exposure.
We live in an age when technological innovation seems to be limitlessly soaring. But for all the satisfying speed with which our gadgets have improved, many of them share a frustrating weakness: the batteries. Though they have improved in last century, batteries remain finicky, bulky, expensive, toxic, and maddeningly short-lived. The quest is on for a “super battery,” and the stakes in this hunt are much higher than the phone in your pocket. With climate change looming, electric cars and renewable energy sources like wind and solar power could hold keys to a greener future...if we can engineer the perfect battery. Join host David Pogue as he explores the hidden world of energy storage, from the power—and danger—of the lithium-ion batteries we use today, to the bold innovations that could one day charge our world.
Professor Iain Stewart uncovers clues hidden within the New York skyline, the anatomy of American alligators and inside Bolivian silver mines, to reconstruct how North and South America were created. We call these two continents the New World, and in a geological sense they are indeed new worlds, torn from the heart of an ancient supercontinent - the Old World of Pangaea.
All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.
The Census of Marine Life - a ten-year effort by scientists from around the world to answer the age-old question, "What lives in the sea?" It was an international effort to asses the diversity, distribution, and abundance of marine life in our ocean, and the project offically concluded in October 2010.
The semantics of the model I'm working from use common goods/common property/ common pool resources (resources used by multiple people) and common property regimes (the institutions or social arrangements between people, the property rights regarding common pool resources).
